A new species,Irura uniprocessa sp. nov.,is described from the Wuliangshan Mountains,Yunnan province.Color photographs and plot drawings of diagnostic characters and comparison with the related species are given. The specimens are deposited in Museum of Tongren University（ MTU）.Irura uniprocessa sp. nov.（ Plates Ⅰ,Ⅱ）Holotype： ♂,Lingbaoshan National Forest Park（ 24. 763 1°N,100. 502 8° E,2 285 m）,Wuliangshan town,Nanjian county,Yunnan province,China,12 August 2015,collected by C. Wang,Z. L. Liao,P. Luo and G. T. Liu（ WC-20150812）.Paratypes： 1 ♂2♀,same data as holotype. 5 ♂,Shidongsi（ 24. 855 1°N,100. 495 0°E,1 781 m）,Laozhu village,Baohua town,Nanjian county,Yunnan province,China,13 August 2015,collected by C. Wang,Z. L. Liao,P. Luo and G. T. Liu（ WC-20150813）.Etymology： The specific name derives from the Latin word ＂uniprocessa＂（ without apophysis）,and refers to the male palp without tibial apophysis. Adjective.Diagnosis： The male of this new species is similar to I. bidenticulata Guo,Zhang Zhu,2011,but can be distinguished from the latter by： 1） the palpal tibia without apophysis but a membranous retrolateral apophysis in I. bidenticulata; 2） the palpal bulb over the retrolateral margin of cymbium but located in alveolus completely in I. bidenticulata. The female is similar to I. hamatapophysis（ Peng Yin,1991）,but can be distinguished from the latter by： 1） the epigyne with a pair of hoods but without hood in I. hamatapophysis; 2） the copulatory openings located at median-posteriorly but closed to genital groove in I. hamatapophysis; 3） the copulatory ducts indistinct but distinct in I. hamatapophysis.Genitals： Male palp of the new species without retrolateral apophysis; cymbial outgrowth relatively slender,sword-like in retrolateral view; embolus slender,originated at 9 o＇clock,and about half the length of the cymbium. Epigyne with a pair of hoods closed to each other situated median-posteriorly; copulatory openings small,situated the bilateral of hoods; copulatory ducts indistinct; spermathecae divided into 2 chambers.
